The equation you use would be 3x+10 = 3x-28
they aren’t linear pairs so it cannot equal 180
Answer:

Step-by-step explanation:
The correct question is
Large cheese pizzas cost $5 each and large one-topping pizzas cost $6 each.
Write an equation that represents the total cost, T, of c large cheese pizzas and d large one-topping pizzas.
Let
T -----> the total cost
c ----> the number of large cheese pizzas
d ---> the number of large one -topping pizzas
we know that
The total cost (T) is equal to the number of large cheese pizzas (c) multiplied by it cost ($5) plus the number of large one -topping pizzas (d) multiplied by it cost ($6)

Answer: The product is 
Step-by-step explanation:
Since we have given that

We need to find the product:
Since we know that

Here, a = x
and
b = 5
So, it becomes,

Hence, the product is
